Specification of iletters Patent.

Patented Mar. 23, 1920.

Application filed May 5, 1919. Serial No. 294,?49.

To all whom it may concern:

Be it known that I, WILLIAM FRANKLIN BRITTAIN, a citizen of the UnitedStates, residing at Troup, in the county of Smith and State of Texas,have invented certain new I tached and collapsed, so that it will notoccupy much space, and may be readily stored away.

A further feature of the invention resides in the provision of a deviceof the character described, which may be also used as a lifting jack.

l Vith the above and other obj eots in view, the invention hasparticular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in thisspecification and illustrated in the accompanying drawings, whereinFigure 1, is a side elevation of the device.

Fig. 2, is a plan view shown partially in section, taken on the line 2-2of Fig. 1, and

Fig. 3, shows the device when applied, as a lifting jack.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, thenumerals 1 and 1, designate the side members of the frame, said membersbeing spaced apart, and at one end, having the outwardly turned portions2, 2, forming a base and secured to the other end of the side member 1,there is the arcuate rack member 3, formed with. the ratchet teeth 4:.Pivoted between said side members, there is the manual operating lever5, provided with the spring seated dog 6, operated in the usual mannerby the actuating rod 7. The other end of this lever is extended, andpivoted to the locking bar 8. One end of this bar is connected to theside members through the links 9, 9, and its other end extends beyondsaid members and carries the transverse locking rod 10, which extendseach way beyond said bar. hen it is desired to use the device forlocking an automobile, the outwardly turned ends 2, 2, are engaged overthe hooks 11, 11, carried by the dash board12, and spaced apart, and thelocking rod is engaged behindthe operating levers 13 and 1d, of thevehicle. The manual lever 5 is then pulled rearwardly, forcing thelocking bar 8 upwardly, and carrying the locking rod 1.0 against saidlever. The dog 6 will engage with the ratchet teeth 4, to hold thedevice in positioii, and the hasp 15 of the lock 16 is then passedthrough alined holes in the rack member 3, and the lever 5, and the locksecured so as to hold said operating levers 13 and 14-, againstmovement.

As shown in Fig. 3, the device is applied as a jack. lVhen employed forthis position, the base rests upon the ground, and the free end of thebar 8 is inserted under the object to be lifted. The operating lever 5is then forced downwardly, forcing the bar 8 upwardly, and elevating theobject sought to be raised.

When used for this position, the dog 6 will engage with. the ratchetteeth 4C, to hold the objects sustained by the jack in elevatedposition.

W hat I claim is:

A device of the character described, comprising a frame, consisting ofside members, spaced apart, said members being turned outwardly at oneend forming a base, a rack formed with ratchet teeth, carried by theother end of said frame, a manual lever pivoted to the frame, andprovided with a dog adapted to cooperate with said rack, whereby themanual lever may be held in fixed position relative to the frame, alooking bar, a link connecting one end of said bar to said frame, alocking rod carried by the other end of said bar and extending each waytherefrom, said bar being pivotally connected to said lever and adaptedto be actuated lengthwise relative to the frame, through themanipulation of said lever.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM FRANKLIN BRIT'IAIN.
